Patent number: 7781328Abstract: A multilayer substrate device formed from a base substrate and alternating metalization layers and dielectric layers. Each layer is formed without firing. Vias may extend through one of the dielectric layers such that two metalization layers surrounding the dielectric layers make contact with each other. The vias may be formed by placing pillars on top of a metalization layer, forming a dielectric layer on top of the metalization layer and surrounding the pillars, and removing the pillars. Dielectric layers may be followed by other dielectric layers and metalization layers may be followed by other metalization layers. Vias in the substrate may be filled by forming an assembly around the substrate, the assembly including printing sheets containing a conductive ink and pressure plates for applying pressure. A vacuum may be applied to remove air in the ink. Pressure may then be applied to the printing sheets through the pressure plates.Type: GrantFiled: October 8, 2007Date of Patent: August 24, 2010Assignee: Medtronic Minimed, Inc.Inventors: Rajiv Shah, Shaun Pendo, Edward B.
